Output Voltage Tables for Stock R1 and R2 Values
Where a very accurate voltage is not required, it is much easier to use standard (stock) resistors to put together an LM317 or LM338 voltage regulator. Below are tables of output voltages for different combinations of the most commonly found resistors.
Vout = 1.25 * (1 + R2/R1)
- 5.80V R1 = 330, R2 = 1200
- 5.88V R1 = 270, R2 = 1000
- 5.91V R1 = 220, R2 = 820
- 5.92V R1 = 150, R2 = 560
- 5.97V R1 = 180, R2 = 680
- 6.04V R1 = 470, R2 = 1800
- 6.06V R1 = 390, R2 = 1500
- 6.32V R1 = 370, R2 = 1500
- 6.46V R1 = 240, R2 = 1000
